Unknown Unknowns: The Problem of Hypocognition

“Consider this: how well can you discern different shades of blue? If you speak Russian, Greek, Turkish, Korean or Japanese, your chances are much better than if you speak English. The former groups have two distinctive linguistic representations of blue. In Russian, for example, dark blue (sinii) and light blue (goluboi) are as distinct as red and pink. But in English, we know blue as a single concept. The deprivation of finer-grained color concepts poses a great perceptual disadvantage. English speakers more easily confuse blue shades, not because we have poorer vision, but because we lack the more granular distinctions in the language we speak.” blogs.scientificamerican.com/observati…
